Heike v. United States

Background

A company secretary was indicted for conspiracy to defraud the government by secretly rigging scales so imported raw sugar weighed less than its true weight. Years earlier, in 1909–1910, he had obeyed subpoenas, produced company records, and testified before a grand jury investigating the American Sugar Refining Company under the Sherman Act. He identified checks, described company ownership, and handed over a table summarizing pounds melted each year. He later claimed a 1903 law (amended 1906) gave him immunity from any prosecution connected to that testimony.

Reasoning

The Court had to decide whether the immunity law protected the secretary from the later revenue-fraud prosecution. The Court read the statute to match the scope of the constitutional protection against self-incrimination, not as a broad amnesty for all related wrongdoing. It emphasized that compelled production of corporate books or summaries the witness could not have withheld is different from protected testimony. The specific testimony and the table did not substantially concern the sugar-weight frauds and did not tend to incriminate him, so the law did not bar prosecution.

Real world impact

The decision lets the prosecution go forward in this case and narrows the scope of statutory immunity in future investigations. Witnesses who produce corporate records or who give only background or summary evidence generally cannot use the 1903–1906 immunity to avoid prosecution for different crimes. The opinion signals that immunity covers testimony that substantially and directly risks self-incrimination, not remote or incidental facts, so compelled evidence in government probes may still be usable by prosecutors.
